AIR- GUN.

Patented sept. 1, 190s.

Application filed. April 12, 1907. Serial No. 367,838.

` a citizen of the UnitedStates of America, re-

' erence being larged longitudinal section t of the gun, illustratingthe construction and siding at Detroit, lin the county of Wayne.

and State of Michigan, have invented certain new and useful'Improvements in Air-Guns, of which the following. is 'a specification,refhad therein to the accompanying drawings.

The` invention relates to an Aair, gun pro-I `Avided with the usualplunger and actuating spring therefor, and consists in the constructionof a firearm of this ty e wherein the compression of the spring antheshifting of the plungerA are eiiected at dierent eriods, instead ofsimultaneously ashereto ore, resulting in a'material decrease in theower required to cock the un, and v.provi ing a iirearm that can beeasily operated.

The invention further consists inthe peculiar arrangementandcombin'ation of the gun parts, and urtherin certain details oiconstruction as will behereinafter set forth.

lIn the drawings,-Figure `1 lis a vertical central?. section through anair un embodying -my invention, partly n Ae evation, the

parts beingshown in the 'posi-tion' Jfor shooting;' `.'2.is a similarview, showing thev gunin't e rocess of cockingl; yFig 3 is an enrough aportion arrangement of the barrel;-

4 is a cross section through the barrel, showing the same m' the loadingposition', and Fig-.5 is a detached perspective view of thereciprocatingI member for compressing the spring, and connections withthe stock.

The .reference-letter K ofthe v"gun,terminating at its forward end in ahollow frame B, slotted in its lower portion, as atC.

D is a -casingppivoted to the frame B of the its stock Eftlie connectionbeing such as to" provide a breakdown construction similar to aVbreech-loading gun, andFrep'r`esents`"the gunbarrel secured to thecasing in a manner to be hereinafter described.` Within the casing D isan air compression cylinder G, in vlhicha plunger I-I of any suitabletype wor s.

designates theusual trigger held in its retaining position by a springR, the trigger` being pivoted to the reciprocating member and carriedwith it during its travel to and k.iro in the casing'.

As the means Jfor reciprocating the memb'er P, a link S is preferablemployed eX- tending through a s ot T in t ie reciprocating member, andhaving a pivotal connection with the latter, and being preferablyconnected at its opposite end to the frame B of the stock, the endportion U of the lever eX-- 4tending',within the opening C of the frame,as

plainly indicated. y

In the o eration of cooking the gun, the stock isl bro en down, asindicated in Fi 2, causing the reciprocating member encirc ing theplunger rod to bear against and compress the spring, theoperationofcompressing being continued luntil the'liook uponfthe pluiif gerl rodengagesy the trigger..v Upon closing the breech of the un,thereciprocatin lmember is retracted, (Irawing with it the p unger, thusshifting the latter` into its shooting posi- The missile is theninserted within the gun barrel, ashereinafter set forth, and the gun isin readiness for use.

Itgvill be obvious from the construction' described that'ai'iy form ofoperating means sov ' position, slightly within the barrel Hush with l5creased leverage that the gun stock in the breaking-down operationproduces.l

The barrel F'referred'to is connected to the casing D in alinement withthe air compression chamber, and is shiftable longitudi- 10 nally of thecasing, and the connections are' Vof such a character that the barrelmay be rocked or shifted out of alinement with the casing into a loadingposition to receive the projectile.- The rear'end of the barrel V isslightly reduced, and adapted to extend a short distance within theforward end of the casin while a pivot-pin W secured to the barreextends within the opening O in the plug section of the casing, andashort distance therebeyond,`termi natin in a head-X. A spiral spring Yis interpose between the head and the plug section, and serves toA holdthe barrel 'normally in alinement with the compression chamber.

To load the gun, t e barrel is adjusted axially of the casing atsufficient distance tov clear the casing end, and then rocked or roftated sidewise into. the position shown in Fig. 4 to permit of theinsertion of the projectile.

InV addition to the pivot-pin W described serving as the main connectionbetween the barrel and the casing, I preferably proportion the parts s`othat the proj ectile-starting rod J will extend, when the plunger is in.the firing the casing end, as plainly shown in Fig. 1, the projectinportion of the rod J constituting additiona securing means for holdingthe barrel in its operative position.

From the foregoing description it will be readily seen that the workrequired in cocking the gun is divided, a part being performed duringthe breaking-down of the stock, and the balance `in restoring the gun tothe shooting position,4 and thus the power necessarily cockin is reducedto a minimum.

Whi e I have shown the preferred mechanism for accom lishing thisresult, I do not wish to be limited thereto, as my inventioncontemplates broadly the shifting of the plunger and the compression ofthe plunger spring at different intervals during the o heretofore withthe attendant disadvantages What I claim as my invention is,'- y 1 In anair g-un, the combination with.a
